Abstract

There is provided a drive unit (10, 110, 210, 310, 410) capable of making a detachment work of the rear wheel (40) from a rear arm (50) easy. An electric wire (64A) structure includes a first electric wire (64A) part extending from an electric motor (30), a second electric wire (64A) part extending along a rear arm (50), and a terminal block (35) for electrically coupling the first electric wire (64A) part and the second electric wire (64A) part to each other. A rear-wheel hub (41) is provided with a support (146, 46) for supporting the rear-wheel hub (41) so as to allow the rear-wheel hub (41) to rotate. The rear arm (50) has a rear case (51) which houses an engaging part between a drive shaft (27) and a transmission shaft (21, 221). The rear case (51) is attached to the support (146, 46) with a screw (35A, 83). The electric wire (64A) structure extends from the rear case (51) toward an inside of the rear-wheel hub (41) passing through an electric wire path (46K, 46M, 51, 53B, 56F) provided to the support (146, 46). The terminal block (35) is located between a left end surface (46N) of the rear case (51) and a right end surface (51) of the rear-wheel hub (41).
